CHA2DS2VASc score tool -Anticoagulation therapy

The CHA2DS2-VASc score is recommended by the National Institute for Health and Care Excellence (NICE) as a tool to determine the necessity of anticoagulation therapy in individuals with atrial fibrillation.

Atrial fibrillation (AF) is the most common irregular heart rhythm disorder, linked to a higher risk of mortality and health issues due to stroke and blood clots. The CHA2DS2VASc Score considers factors such as congestive heart failure, hypertension, age, diabetes, stroke history, vascular disease, and sex. Utilizing this score enhances patient care by guiding evidence-based decisions on anticoagulation therapy, reducing the risk of thromboembolic events.

However, this risk varies among individuals and can be assessed more accurately using the CHA2DS2-VASc score, which stands for congestive heart failure, hypertension, age, diabetes mellitus, prior stroke or transient ischemic attack (TIA), vascular disease, age, and sex category.

The CHA2DS2-VASc score is an expanded version of the CHADS2 score, considering factors like age, medical history, gender, clinical risks, and other health conditions that contribute to the risk of ischemic stroke.

Both the European Society of Cardiology and the American College of Cardiology/American Heart Association Task Force on Practice Guidelines and the Heart Rhythm Society endorse the use of the CHA2DS2-VASc score for managing atrial...
